I think Tyson would have great chances vs Chris Arreola or Stiverne.

But

Tyson never once beat anybody as big +good as Arreola

Or as good+heavy as Stiverne

So to answer your question, I DO rank Tyson ahead of these guys, but whether he would win against them in fact is an open question.

One thing is for sure, Tyson was stretched to the limit by guys whom either of these guys would have banged straight out. So no, Tyson could not steam roll either of them.

I still rate Arreola just a notch below Stiverne now, they are rather evenly matched.

Considering Tyson vs these guys is a valid question because he WAS special.

No pre80's HW was special, the better ones won against bums and cruisers mainly! With little exception.

Pre80's HW's could barely even box as we would describe it today.
